Title: Three=dimensional impression on record carrier - with metal layer underlying photosensitive layer on substrate
Inventor: ZEHENDER ERNST DIPL PHYS DR
IPC: G11B23/00
Filed: 1977-05-13
Abstract: The surface of the carrier first receives a metal layer of a thickness to suit the desired depth of impression, by vapour deposition or by a wet currentless method (copper on glass). The photo layer is applied to this and exposed through a mask. After dissolving the exposed sections of the photo layer, the accessible sections of the metal alyer are etched away and the remaining sections of the photo layer can be removed. The uniformity and thickness of the photosensitive layer are less important using the above method and also the withdrawal of the press tool from the impression is facilitated.

Title: Gas turbine for vehicle propulsion - has thermostatically regulated auxiliary turbine to turn compressor
Inventor: EARNEST ERNEST ROBERT
IPC: F01K25/08
Filed: 1977-07-12
Abstract: The exhaust heat from the output turbine (20) is used to raise the temp. of an organic working medium such as toluene or pyridene which is used to drive a closed cycle turbine (26). The turbine and the main compressor (14) are fitted to a common shaft (28) which extends through the compressor (14) to drive the auxiliaries via a gear box (30). The closed cycle turbine (26) is regulated by a thermostatic throttle valve (40) located in the passage (42) leading from the heat exchanger (22) to the turbine (26). The combined performance level of the two turbines is regulated by varying the fuel flow to the output turbine (20) and the compressor air inlet flow via a throttle valve (16). The two factors are controlled by a hydro mechanical or electronic regulator (52) responding to a required output signal and signals from a turbine inlet temp. sensor (54).
Patent DE-2733612-A1 (DE)
Title: Dowel with tapered plug for fixing objects to walls - is expanded radially by shank of bolt engaging internal ridge
Inventor: KOENIGER RUDOLF ING GRAD
IPC: F16B13/06
Filed: 1977-07-26
Abstract: The dowel (2) has a tapered bore at one end to receive a tapered plug (3) which has an internal screw thread (90). The other end of the dowel (2) has an internal helical ridge (45) and short external ribs (6). When the dowel is fitted into a through hole in a wall and a bolt inserted, the bolt thread engages the helical ridge (45) until the bolt is forced into the thread (90), since the ribs (6) prevent rotation of the dowel. Further rotation of the bolt forces the plain portion of the bolt shank into the reduced diameter at the helical ridge (45). The end section of the dowel is expanded radially and grips the surface of hole in the wall.

Title: Increasing the speed of fluid-jet looms - by simultaneous weft insertion from both sides of loom
Inventor: SCHEFFEL WALTER
IPC: D03D47/28
Filed: 1978-06-12
Abstract: An arrangement of weft- inserting devices for a loom using fluid-jet weft insertion, whereby picks are inserted simultaneously from opposite sides of the loom to produce two widths of cloth side-by-side with a central space between. Width variations are obtd. by varrying the size of the central space, the outer edges remaining fixed. The use of two devices inserting half-length picks means that the energy consumption of each jet, and the acceleration of the leading edge of the pick, is reduced by one half, giving neater, more reliable introduction into the shed. It also allows the number of insertions per min. to be increased, giving improved productivity.
